WHIFFLETREE.

Specification of Letters Patent.

Patented Apr. 2?, 1915.

Application filed February 21, 1914. Serial No. 820,201.

To all whom may concern Be it known that I, BENNIE P. HANsoN, citizen ofthe United States, residing at Monticello, in the county of Jones andState of Iowa, have invented certain new and useful Improvements inWhiiiietrees; and 1 do hereby declare the following to be a full,

clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to metallic whiiile trees and the objects of myinvention are to have a whiiie tree that is exceedingly strong, durable,light and compact.

I obtain these objects by means of the device shown and illustrated inwhich,

Figure 1 is an elevation with one portion shown in section. Fig. 2 is asectional view on the line 2-2 of Fig. 1. Fig. 3 is a sectional view onthe line 3-3 of Fig. 1. Fig. 4 is a modification adapted to the clevisstructure. Fig. 5 is a side elevation of a slightly modified form of thedouble tree.

For my device 1 take two flat metallic bars 1 and 2 respectively, swagetheir edges intermediate of their center and end as shown in Fig. 1.Between said bars I place a metallic box-like structure 3 formed of a'Hat piece of metal bentto box formation, one end 4 of which overlappingthe other end 5. At suitable points are apertures 6 for the purpose ofattaching the box between said bars 1 and 2 by means of bolts or rivets7 as shown in Fig. 1 of the drawings. Registering apertures 8 throughsaid bars 1 and 2 and box 3 are placed in the center thereof for theinsertion of a clevis or king bolt. Like boxes 9 and 10 are insertedbetween the ends of said bars 1 and 2. Said boxes 9 and 10 are ofsmaller dimensions than the center box 3 which allows of a bridgeformation in the assembling of said members 1 and 2 adding to thestrength of my structure. 1n like manner are registering orifices 11therethrough for the insertion of a clevis bolt 12 as fully shown inFig. 2. Midway between the center and ends of my whiiile tree Ireinforce my device by means of bolts 13 run through sleeves 14.

My swingletree is of like construction with the exception that 1 havehooks 15 placed between the bars at the end thereof, said hooks beingcurved to suitable formation on their portions extended beyond theswingletree. These hooks perform the same function as the boxes 9 and 10on my double tree and are attached thereto by means of registeringoriiices 16 through which are run bolts 17, said swingletree I attach,in one form, to the double tree by means of the clevis 18 and clevisbolt 12 as heretofore noted.

A modified structure of swingletree is had as illustrated in Fig. 4wherein slots 19 are cut into the bars 1 and 2 previous to swaging andassembling so that when assembled the slots which register becomeapertures for the insertion of retaining eyes 2O which hold the tracehooks 21. In the center of my modified structure, I bend intoapproximately rectangular form my box like structure 22 of any suitablemetallic structure, as shown, having extensions or lugs 23 and 24 withapertures therein for the insertion of a clevis bolt 25.

Referring to the modied construction of the doubletree shown in Fig. 5,the numeral 40 indicates the tree bar and is formed straight or planeand with or without swaged edges, as the bars 1 and 2. The bottom bar 41is secured in spaced relation at its medial portion to the correspondingportion of the topk bar 40 by suitable bolts or rivets 42 extendingthrough spacing sleeves 43. The portions of the bars 40 and 41 at andadjacent the ends are secured together by bolts or rivets 44 positionedthrough sleeves 45, and as clearly shown the extreme ends are drawnclose together. The central rivets 42 are spaced a proper distance apartto accommodate the wagon tongue 46 to which the doubletree is secured bya king bolt or the like 47 extending through apertures in said tree andin said tongue.

Of course I do not limit my structure to the exact form and 'shape ofwhich I have herein shown, but wish to have it understood that I maymake such minor differences in the following embodiments of my inventionas shall lie within the scope of the .appended claim. For instance I canhave a greater number of reinforcing bolts 13 and sleeves 14 or I canhave a greater multiplicity of boxes such as 3, 9, 10 and 22respectively than what 1 have shown. This device allows of easyoperation and will stand great strain.

That 1 claim is:

A whifle tree composed of a double tree having svvagedv top and bottommembers rc end, registering orifices through said Whiie tree and saidreinforcing devices for the insertion ofy a clevis, ay swingletree oflike structure superposed above'said double tree having registeringapertures therethrough,

a clevis coupling said double tree and said i3 lswingletree together. l

In testimony whereof I havesigned my name to this specification in thepresence of tWo subscribing Witnesses.
